摘要(Abstract):

为了建立玛咖定性、定量标准,参照2010年版药典附录相关方法,分别对玛咖的水分、浸出物、总灰分、酸不溶成分、重金属含量进行了测定;以玛咖中特征性酰胺类成分亚油酰胺为指标性成分,分别采用TLC和HPLC进行定性鉴别和含量测定研究。结果显示,玛咖中亚油酰胺的薄层色谱鉴别特征明显,专属性强;含量测定线性范围为0.01~2.00μg(r=0.999 8),平均回收率(n=9)为99.27%(RSD 2.0%)。所建立的玛咖定性鉴别和定量测定方法简单准确,能够为玛咖的质量控制提供有效数据。
To control the quality of Maca,the quality standard was established in this study. According to the methods recorded in the Appendix of Chinese Pharmacopoeia( 2010 Edition),the water,extract,total ash,acid insoluble substance,and heavy metals inspections in Lepidium meyenii were carried out. N-benzyl-9Z,12Z-octadecadienamide in L. meyenii was identified by TLC,and it was determined by HPLC. The results showed that the N-benzyl-9Z,12Z-octadecadienamide identification of TLC was a strong mark and specificity. In content determination experiment,the linearity of N-benzyl-9Z,12Z-octadecadienamide was in the range of 0. 01-2 μg( r = 0. 999 8),and the average recovery( n = 9) was 99. 27%( RSD 2. 0%). The methods were simple,accurate,with good reproducibility. It is suitable for quality control L. meyenii.
